Mitigation PFHxA-induced neurotoxicity in Carassius auratus brain cells by selenium-enriched Bacillus subtilis via the BDNF/PI3K/AKT/GSK-3β pathway.

As emerging contaminants growing threat to aquatic organisms, explore effective mitigation strategies is particularly important. Our previous studies have shown that selenium-rich Bacillus subtilis can not only alleviate the cause of brain damage by perfluorohexanoic acid (PFHxA) in Carassius auratus via the intestinal axis of the brain, but its metabolites can also alleviate PFHxA toxicity. This study further explores the potential mechanism through in vitro experiments.

Upregulation of HLA-II related to LAG-3CD4 T cell infiltration is associated with patient outcome in human glioblastoma.

Glioblastoma (GBM) is the most common malignant diffuse glioma of the brain. Although immunotherapy with immune checkpoint inhibitors (ICIs), such as programmed cell death protein (PD)-1/PD ligand-1 inhibitors, has revolutionized the treatment of several cancers, the clinical benefit in GBM patients has been limited. Lymphocyte-activation gene 3 (LAG-3) binding to human leukocyte antigen-II (HLA-II) plays an essential role in triggering CD4 T cell exhaustion and could interfere with the efficiency of anti-PD-1 treatment; however, the value of LAG-3-HLA-II interactions in ICI immunotherapy for GBM patients has not yet been analyzed.

Expression, clinicopathological significance, and prognostic potential of AMPK, p-AMPK, PGC-1α, and TFAM in astrocytomas.

AMP-activated protein kinase (AMPK) is a sensor of energy status that maintains cellular energy homeostasis. Activation of AMPK enhances the expression of proliferator-activated receptor γ coactivator 1α (PGC1-α) and subsequently activates mitochondrial transcription factor A (TFAM) to regulate mitochondrial oxidative respiratory function. The possible functions of AMPK, p-AMPK, PGC-1α, and TFAM and their interactions in astrocytomas are not known.

Association of ambient air pollution and pregnancy rate among women undergoing assisted reproduction technology in Fujian, China: A retrospective cohort study.

α-lipoic acid ameliorates hepatotoxicity induced by chronic ammonia toxicity in crucian carp (Carassius auratus gibelio) by alleviating oxidative stress, inflammation and inhibiting ERS pathway.

High environment ammonia (HEA) poses a deadly threat to aquatic animals and indirectly impacts human healthy life, while nutritional regulation can alleviate chronic ammonia toxicity. α-lipoic acid exhibits antioxidative effects in both aqueous and lipid environments, mitigating cellular and tissue damage caused by oxidative stress by aiding in the neutralization of free radicals (reactive oxygen species). Hence, investigating its potential as an effective antioxidant and its protective mechanisms against chronic ammonia stress in crucian carp is highly valuable.

Transcriptome analysis reveals the mechanism of the effect of perfluorocaproic acid exposure on brain injury in Carassius auratus.

Perfluorocaproic acid (PFHxA) has received much attention as an emerging pollutant linked to neurological problems in humans and fish. However, the potential mechanism remains unknown. In this study, the pathological damage to tissue sections demonstrated that perfluorocaproic acid caused brain tissue damage, and the increased antioxidant index malondialdehyde (MDA) and decrease in superoxide Dismutase (SOD), acid phosphatase (ACP), alkaline phosphatase (AKP), glutathione peroxidase (GSH-Px), Catalase (CAT), and Lysozyme (LZM) that perfluorocaproic acid activated antioxidant stress and caused brain damage.

Infection of epithelioma papulosum cyprini (EPC) cells with spring viremia of carp virus (SVCV) induces autophagy and apoptosis through endoplasmic reticulum stress.
